METAL BARREL.

SPECIFICATION forming part of Letters Patent No. 793,579, dated June 27,1905.

Application fil d September 18, 1902. Serial No. 123,872.

To (all whom/ it TII/IJ/Z/ concern.-

Be it known that 1, ROBERT H. HACKNEY, a citizen of the United States,residing at Milwaukee, in the countyof Milwaukee and State ofl'Visconsin, have invented certain new and useful Improvements in MetalBarrels, of which the following is a specification, reference being hadto the accompanying drawing, forming a part thereof.

The object of this invention is to produce a light, strong, and durablemetallic barrel or keg with a smooth interior that will not catch andhold sediment and that can be easily and thoroughly cleaned.

The invention consists in certain novel features of construction and inthe arrangement and combinations of parts hereinafter particularly setforth and claimed.

The accompanying drawing shows, partly in side elevation and partly incentral longitudinal section, a barrel embodying the aforesaidinvention.'

The body a of the barrel, formed by dies or other suitable meansintegrally with one of the heads 5 without seam or joint from a singleblank or steel plate, is primarily made cylindrical. The proper taper toproduce the bilge is given by suitable dies to that part of the bodynext to the closed end or head, while the other part of the body next tothe open end remains cylindrical and of a diameter equal to the diameterof the barrel at the bilge. The metal of the body isv then compressed ordrawn in gradually by means of suitable dies from the center toward theopen end to produce a taper corresponding with that from the centertoward the head I), and thus complete the bilge. The edge of the bodynext to its open end is then preferably bent or flanged inward, as shownat 0, for the attachment thereto of the separately-formed head (Z. "L.lge or the required taper therefor in c. l of the body may, however, beproduceu spinning or rolling.

The foregoing operations, performed in the order above mentionedsubstantially as explained, admit of forming the body with a bilge at ornear the middle and a head at one end in one piece, without seams,joints, or corrugations. The head 01 is preferably forged at itsperiphery with a groove or fold in which the inturned edge 0 of the bodyis inserted and secured. The groove in the head (Z is primarily made orleft sufliciently open to receive the inturned edge 0 of the body. Thehead is then placed in a cup-shaped or other suitable contracting-die,and the open end of the body is forced into this die, which turns theedge of the body into the groove in the head, closing the groove at thesame time.

To reinforce the barrel at the ends, to cover and protect the jointbetween the body and head (Z, and to avoid internal grooves or pocketswhich catch and retain sediment and dirt, the barrel is provided withannular bands 0 e, which are preferably drawn, pressed, or otherwiseformed from sheet metal, to lit over the ends of the body and to projecttherefrom beyond the heads, against which they have an inturned bearing.The parts of these bands projecting beyond the heads of the barrel formannular rims or flanges corresponding with and serving the purpose ofthe chimes of ordinary wooden barrels.

By the construction herein shown and .described a very strong, light,and durable receptacle is produced, suitable for all the purposes forwhich ordinary barrels are made and used.

The barrel may be provided with metal bung-bushings like or similar tothose used in wooden barrels, and, if desired, the body may be furtherreinforced and protected by bands applied thereto between the end bandsor chime-pieces e.

One great advantage of the construction herein shown and described isthat it presents a smooth surface inside of the barrel, and therebyavoids catching and retaining sediment and dirt and facilitatescleaning.

Various modifications in minor details of construction may be madewithin the principle and intended scope of the invention.

I claim 1. A barrel havinga seamless wrought-metal body with a bilge anda head formed in one piece without seam, joint or corrugatiomand aseparately-formed metallic head joined to an inturned edge of the bodyat the end opposite the integral headsubstantially as described.

2. A barrel comprising a seamless Wroughtmetal body formed in one piecewith a bilge and with an inturned edge at one end, and a metallic headhaving a groove in its periphery in which the inturned edge of the bodyis inserted and secured, substantially as described.

3. A barrel havinga seamless wrought-metal body formed in one piece witha bilge, metallic heads and separately formed metallic chimesoverlapping the body at the ends and projecting parallel with the bodybeyond the heads against which they are bent back, the ends of the bodybeing turned inwardly across the internal recesses in the chimes to meetthe ROBERT H. HACKNEY.
